How do you find the maximum height of a free falling object?

y = v 0 2 − 2 g = ( 2.0 × 10 2 m / s ) 2 − 2 ( 9.8 m / s 2 ) = 2040.8 m . This solution gives the maximum height of the booster in our coordinate system, which has its origin at the point of release, so the maximum height of the booster is roughly 7.0 km.

How do you find the value of g in free fall method?

When the ball is released a timer is started. When the ball hits the trapdoor the timer is stopped. If the distance from the ball to the trapdoor is measured the acceleration due to gravity (g) can be calculated. Use the formula; s = ut + ½at² and note that u = 0 and a = g.

How do you find the acceleration of a free falling object?

How do you find free fall acceleration of a planet?

1. Estimate the total mass of the planet in kilograms.
2. Estimate the radius of the planet, from its center to its surface, in meters.
3. Divide the total mass by radius squared.
4. Multiply the result by the universal Gravitational constant, 6.67×10-11 N·m2·kg-2.

How G can be determined?

The value of G was not experimentally determined until nearly a century later (1798) by Lord Henry Cavendish using a torsion balance. Once the torsional force balanced the gravitational force, the rod and spheres came to rest and Cavendish was able to determine the gravitational force of attraction between the masses.

What is G in free fall?

the value of g is 9.8 meters per square second on the surface of the earth. The gravitational acceleration g decreases with the square of the distance from the center of the earth. Knowing the acceleration, we can determine the velocity and location of any free falling object at any time.

What is the acceleration of an object after 2 seconds?

By 2 seconds after it starts falling, its velocity is 19.6 m/s (9.8 m/s + 9.8 m/s), and so on. The acceleration of a falling object due to gravity is illustrated in the Figure below.

How do you calculate the acceleration of free fall?

Therefore, it is theoretically straightforward to determine the acceleration of free fall simply by dropping something and measuring the time it takes to hit the ground. Experimentally, however, it is exceedingly difficult to get precise-enough times for meaningful results.

What is the value of ‘G’ for free fall?

The value of ‘g’ will tend towards 9.8ms-2 as the distance of the freefall is increased as the accuracy increases when distances increases. Independent variable: The distance of the free fall.

What are the variables in a free fall experiment?

The distance between the ball and the floor to where it is dropped. Dependent variable: The time taken for the ball to reach the ground. Constant variable: The ball, the ruler used to measure the height of the fall, the stopwatch, the room in which the freefall was done. Take a rubber ball and a metre rule.

What is the value of ‘G’ when the distance increases?

The value of ‘g’ will tend towards 9.8ms-2 as the distance of the freefall is increased as the accuracy increases when distances increases.
